Mallinckrodt Announces Study Demonstrating Effectiveness of ECP Immunomodulation, as an adjunct to local standard therapy, in Treatment of Lung Transplant Patients with Bronchiolitis Obliterans Syndrome (BOS)

-- Retrospective study  shows that ECP when added to standard local therapy improves survival probability  by approximately 30% in lung transplant patients diagnosed with BOS compared to  matched controls --

-- Adjunct ECP  therapy also shown to lower hospital-related expenses for BOS patients --

STAINES-UPON-THAMES, United Kingdom, 5 April 2019 --  Mallinckrodt plc (NYSE: MNK), a leading specialty pharmaceutical company, announces  the presentation of a retrospective study that demonstrates the effectiveness  of Extracorporeal Photopheresis (ECP), as an adjunct to local standard therapy,  in lung transplant recipients with Bronchiolitis Obliterans Syndrome (BOS)1.

The study, led by Dr. Christian Joukhadar of  J&P Medical Study Ltd., will be delivered in an oral presentation on  Friday, 5 April, 2019 at the 39th Annual Meeting and Scientific  Sessions of the International Society for Heart and Lung Transplantation  (ISHLT) in Orlando, Florida, USA. Mallinckrodt supported the publication of the  study.

Dr. Joukhadar's work addressed the use of ECP  at the Medical University of Vienna as an empiric treatment option for lung  transplant recipients suffering from BOS. The study sought to evaluate  hospital-related costs and the clinical value of ECP when applied as an adjunct  to the local standard therapy of BOS compared to standard treatment alone.  UVAR XTS™ was the ECP technology  used in this study.

The retrospective study reveals that,  compared to standard BOS-directed therapies alone, the addition of ECP significantly  improves survival probability in double-lung transplant patients diagnosed with  BOS. Over the observation period of up to 15.5 years, survival probability was  improved by approximately 30% in the ECP-treated patients as compared to  matched controls.2

In addition, it was found the addition of ECP  to standard therapy exerts a substantially positive impact on the number of  total re-admissions to the hospital, the total days of care, and the total  patient days, as compared to treatment with standard therapy alone. The study concludes  "ECP has proved highly effective and cost saving in the treatment of lung  transplant patients presenting with BOS." 3

"Mallinckrodt,  a pioneer in the development and delivery of ECP immunomodulation, is pleased  to see this study's evidence of the clinical efficacy in lung transplant recipients with BOS,  and the notable cost savings this therapy can provide for hospitals,"  said Steven Romano, M.D., Executive Vice President and Chief Scientific  Officer of Mallinckrodt. "We are proud to support efforts to evaluate ECP  in this critical area of patient care.
